+
+```java
+@Configuration
+public class MyBatisConfig {
+
+  @Bean
+  public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {
+    SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
+    factoryBean.setDataSource(dataSource);

+
+    // Setting configuration property
+    org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration();
+    configuration.setMapUnderscoreToCamelCase(true);
+    factoryBean.setConfiguration(configuration);
+
+    return factoryBean.getObject();
+  }
+}
+```
+
+<span class="label important">NOTE</span>
+This configuration class must be located within a package scanned by the Spring container (e.g., within the main application package). The class name itself (e.g., `MyBatisConfig`) is arbitrary; only the `@Configuration` annotation is required.
